Did you know...
... that today is Pencil Eraser Day? On this day in 1858, Hyman Lipman patented a pencil with an attached eraser. Yes, folks, we can all thank Hyman for allowing us to erase our mistakes! What's interesting is the eraser was actually installed "within" the wood of the pencil opposite from the writing end so the pencil could be sharpened on both ends to refresh either the graphite core or the eraser.
